About me

Hi! I am a second-year PhD student at the Department of Electrical and Electronic Engineering, Imperial College London, supervised by Dr Aaron Zhao. I am also a memeber of the DeepWok Lab. My PhD research topic is to explore representation learning on higher-order graphs. My long-term research interest is to push the ability of machine learning systems in learning more complex data structures, while reducing their reliance on specialised human knowledge on specific tasks. In June 2022, I graduated as an MEng in Computer Science from Trinity College, University of Cambridge, with a result of distinction, and was awarded the Senior Scholarship.

Outside of academics, I am a keen clarinettist, a 1st Dan kendoka, and a goalkeeper. I am a former member and soloist of the Cambridge University Chinese Orchestra Society, and performed in the orchestra’s Michaelmas Recitals and Annual Concerts in 2018, 2019, 2020 and 2022. I am also a member of the Imperial College Kendo Club and a former member of the Cambridge University Kendo Society, where I won the 2nd Place in the team matches in the 2020 University Taikai, and the 1st Place in the kyu-mixed individual matches in the 2023 Oxbridge Kendo Varsity matches.
